Unclear how to read cookie properties and use in conditionals -

Question

I'm using js-cookie:

It's easy to set a cookie, but I'm unclear how to output specific values and test against them. This works fine:

Cookies.set('newsletter', 'show', { expires: 30, path: '/' });
var myCookie = Cookies.get('newsletter');

But this does not:

if(myCookie){
  var p = Cookies.get(['expires']);
  document.write(p);
}

How do I access the expires property?

According to this issue it is not possible

It‘s not possible.

Also in the FAQ it states the same thing:

It's not possible. Once the cookie has been written, its attributes can‘t be read out. The underlying API we‘re constraint to use doesn‘t support this: https://developer.mozilla.org/en-US/docs/Web/API/Document/cookie
